How we test

Simple terms

What TB-500 does in the body

A laboratory fragment of thymosin β4 — the spare-parts box cells use when they crawl and close a gap.

Cells move by assembling and taking apart actin filaments, the internal scaffolding. Thymosin β4 holds a reservoir of actin ready for the next step. TB-500 isolates that idea so a scratch assay or migration experiment can ask one question cleanly. It is not BPC-157 under another name.

It puts the actin-binding idea on the bench so you can watch a cell crawl, fill a scratch, or re-epithelialise in a named model. BPC-157 is a gut-and-vessel story. This is a cytoskeleton story.

What the work looks at

  • Cell movement and wound-edge crawl
  • Actin, the cell’s internal scaffolding
  • How tissue fills a gap after injury in published models
  • Corneal and muscle-repair literature that names thymosin β4

Hypothetical research neighbourhood

  • Soft-tissue injury models

    Scratch assays, muscle and dermal repair papers that name thymosin β4 / TB-500.

  • Corneal and wound-edge work

    Re-epithelialisation literature. Not a first-aid kit.

  • Fibrosis questions

    Ac-SDKP and actin-buffering show up in anti-fibrotic papers. Adjacent, not interchangeable with BPC-157.

Drawn from published cell and animal work. Hypothetical research neighbourhood — not a diagnosis, not a medicine, not a protocol. This vial is labelled for research use only.

Hypothetical research reconstitution

How this vial is typically mixed

Hypothetical research reconstitution for the named catalogue vial. Not a protocol, not medical advice, not a use instruction. These amounts sit in published and commonly cited laboratory ranges. The vial is labelled for research use only — not for human or veterinary administration.

How often
Twice weekly for four weeks, then once weekly
4–6 weeks loading, then a weekly hold if the assay continues

Bench steps

  1. Let the vial sit until it is no longer cold to the touch.
  2. Wipe the stopper with 70% isopropyl alcohol. Let it dry.
  3. Draw 2 ml bacteriostatic water (0.9% benzyl alcohol).
  4. Run the water slowly down the inside glass — do not blast the cake.
  5. Roll between finger and thumb until the cake is gone. Do not shake.
  6. Label the date. Store the solution at 2–8 °C. Do not freeze. Use within 30 days unless the note below says otherwise.

Thymosin β4 fragment. The literature uses milligrams, not micrograms — do not treat it like BPC-157. Same fridge rule.

Bacteriostatic water and sterile syringes ship with peptide orders over £75. Kit details · 10 ml bacteriostatic water

What this is

Buy TB-500 10mg, the research analogue built around the LKKTETQ actin-binding motif of thymosin β4, the principal G-actin sequestering peptide. Sequence and mass on the certificate. Characterise it in your own scratch assay and migration work.

Laboratory handling

Lyophilised solid. Keep refrigerated, dry and dark. Reconstitute under aseptic laboratory technique with bacteriostatic water. For in-vitro research only — not for human or veterinary use. Peptide orders over £75 include the sterile kit.

Journal

TB-500 and thymosin β4: repair is a cytoskeletal programme

Cells crawl by parking and releasing actin monomers. Thymosin β4 is the buffer. TB-500 is the research analogue built around that idea — characterised, named, on the bench.

About TB-500

How is TB-500 different from BPC-157?

Different molecule, different job. TB-500 is built around the LKKTETQ actin-binding motif of thymosin β4 — a cytoskeletal / migration probe. BPC-157 is a gastric pentadecapeptide. Treating them as interchangeable is a category error; serious benches keep both.

What does TB-500 do in the body?

A laboratory fragment of thymosin β4 — the spare-parts box cells use when they crawl and close a gap. In published cell and animal work — not a use instruction. TB-500 10mg is labelled for research use only, not a medicine.

Is TB-500 for human use?

No. TB-500 10mg is labelled FOR RESEARCH USE ONLY. NOT FOR HUMAN CONSUMPTION. It is a laboratory reagent, not a medicine, food or cosmetic.

What purity and identity do you publish for TB-500?

≥98% HPLC. CAS 885340-08-9. Sequence LKKTETQ motif / Tβ4 analogue. Mass ~4.9 kDa (full Tβ4 analogue). Method HPLC.

How fast does a UK order arrive?

Next-day tracked UK delivery is £5 on every order. Discrete laboratory mailer. UK addresses only. Guest checkout — you get a PP- order ID and a tracking number.

Does this vial include the reconstitution kit?

Peptide orders over £75 include USP-grade bacteriostatic water and individually packaged sterile syringes. Under £75 the vials ship without the kit. The kit is a laboratory accessory, not a protocol.
